Bontrager Air Support HP Pro

Extend the hidden hose on Bontrager's Air Support HP Pro pump, and thread it onto your Presta valve for secure inflation of your tires. Built with a smaller volume chamber for higher-pressure tires, this premium pump allows you to effortlessly inflate tires up to 120 psi. Available in two lengths: Long for more air per stroke, or Short for an easy fit into a jersey pocket.

This pump worked the first day I bought it. Flatted in group ride. Pumped worked great that time.
Fast forward a few months and the pump is called for. Pumped over 200 strokes and can't get over 30 psi. Tested it on several tire sizes after I got home with same results. It barely inflated just the tube with no tire. Going back to CO2's.

I bought this in the fall and got about 20 uses out of this as of July 2015 (I used it in to repair about 5 flats, and then about 15 other times). I expected it would last longer than 5-6 months (I don't bike normally in the winter). The top metal clamp that holds the hose to the air delivery piece that you put on the bike broke off, meaning the hose got stuck in the pump, rendering it useless.
